COP-TUBE.

Application filed November 19, 1906. Serial No. 344.136.

To @HJM/1,0771, it r11/tty concern:

Be it known that I, EDMOND H. GUERzN, a citizen of the United States,residingl at Toonsocket, in the county of Providence and State of RhodeIsland, have invented new and useful Improvements in Cop-Tubes, of whichthe following is a specification.

My invention pertains to cop-tubes of the kind that are formed of coiledsheets of paper or other pliable material and are provided at pointsintermediate their ends with reinforcing-rings designed to serve theadditional office of lessening the liability of the yarn slipping orbeing pulledoff the tube incident to handling thereof and it consists inthe peculiar and advantageous cop-tube hereinafter described, andparticularly pointed out in the claim appended.

In the accompanying drawings, forming part of this specification,Figurell is a plan view of the prepared sheet from which the cop-tubeconstituting the preferred embodiment of my invention is formed. Fig. 2is an elevation of the cop-tube formed and ready for use. Fig. 3 is atransverse section taken in the plane indicated by the line 3 3 of Fig.2.

Similar letters of reference designate corresponding parts in all of theviews of the drawings.

In carrying out my invention and producing my novel cop-tube I take asheet A of pliable material, preferably paper, and give it the shape inoutline shown in Fig. l and provide it at one of its long edges with aplu- -rality of tongues B, which are gradually increased in length asthey recede from the narrow end of the sheet and approach the wide endthereof. I then apply suitable adhesive to the sheet A in the mannercommon to the manufacture of this type of cop-tube, after which,starting with the plain long edge C of the sheet, I coil the said sheetinto the form shown in Figs. 2 and 3. rIhis will place the tongues B atthe outer side of the cop-tube, and incident to the completion ofSpecification of Letters Patent.

Patented March 12, 1907.

the coiling of the sheet the said tongues are wound around and fastenedby adhesive to the outer coil of the sheet, so that their free ends meettheir heels, or tlie points at which they are joined to the sheet. Asthus arranged the tongues B obviously forni rings which serve toreinforce and lend strength to the coiled tube and at the same time areadapted to catch and hold yarn against longitudnal movement on the tubeand in that waylessen the liability of the yarnbeingpulled off the tubeincident to handling thereof.

The rings B may be arranged to extend at right angles to the length ofthe cop-tube, as shown, or at any other angle compatible with thepurpose of my invention without involv ing departure from the scope ofmyinvention.

By virtue of the reinforcing and yarnholding rings B being formed oftongues integral with the sheet of pliable material A it will beapparent that the said rings are formed and secured on the remainder ofthe tube by the coiling of the tube, which contributes materially tocheapness of production, and it will also be apparent that the saidrings B are not, like the separately-applied rings eX- tant, likely tobe displaced from the tube. and become entangled in the yarn.

Having described my invention, what I claim, and desire to securebyLetters Patent, 1s-

A cop-tube composed of a sheet of pliable material coiled upon itself,one edge 0f safd sheet extending longitudinally of the eX- terior of thetube and having tongues at intervals of its length which eXtend'entirelyaround the tube and form rings for reinforcing the tube and holding yarnagainstlongitudinal movement on the tube.

In testimony whereof Ihave hereunto set my hand in presence of twosubscribing Wit- IIGSSGS.
